ICE-CUTTING MACHINE.

SPECIFICATION forming part of Letters Patent No. I7'5-`3,519, dated March 1, 1904.

Application iiled October 17, 1903. Serial No. 177,493. (Ilo model.)

To all whom it may concern:

Be it known that I, HERMAN REINHOLD, a citizen of the United States, residing at Davenport, Scott county, Iowa, have invented a new and useful Ice-Cutting Machine, of which the following is a specification.

My invention relates to improvements in ice-cutting machines in which large cakes or blocks of ice are cut by saws into small cubes or blocks; and thegeneral object of my invention isto provide means by which the saw is guided and supported without interference with the necessary set of the saw-teeth. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- -Figure 1 is a top -or plan view of the machine. Fig. 2 is a side elevation. Fig. 3 is an end elevation showing the brace-block and one tube partly in section. Fig. 4 shows the saw, guide-bars, and roller-bearing in detail. Fig. 5 isa detail of the caps. Figs. 6 and 7 are details of the slotted guide-bars, Fig. 6 with one side removed. Fig. 8 is a detail of the stop-nut. Fig. 9 is a detail of langes on bottom of bed-plate.

Similar letters refer to similar parts throughout the several views.

rIhe table or bed-plate E, with its legs X, the longitudinal brace D, and slotted tubes A and B constitute the framework of the ma-l chine.

The bed-plate E has secured around its edge with the surfacel of the latter beneath the slot- The portion of each tube eXtend` ted tubes. ing above the bed-plate is slotted longitudinally on opposite sides to permit the passage of the saw-blade. The saw-blade O is provided with slots O' and C", each of which is fitted to receive a roller or bearing c", pivoted at c' in the slots of the guide-bars c.

The upper ends of the tubes A B are thread.-

ed to receive caps A' B', and each cap is provided with a tapering plug A", which enters the end of the tube 'and maintains the sides'of the tube at a constant distance apart. The guide-bars lit closely and slide readily in the tubes and are provided with anges 7c,- which lit in the slots of thetube 'and prevent the guide-bars from turning or binding. The lslots in the guide-bars are just large enough to permit the easy passage of the saw-blade back and forth through them, while the slots in the tubes are large enough to permit the unimpeded passage of the saw-teeth when given a wide set. The tube B is braced by a longitudinal brace-block D, throughl which it passes. The slot in the end of the saw-blade passing through the tube B is somewhat shorter than the slot in the other end of the saw-blade and so disposed that the impact at the end 'of leach stroke of the saw comes upon the braced tube B. The tubes A and B are each provided with an -o'val longitudinal slot a, through which passes a thumb-screw c', which screws into a stop nut or lug a" on the inner side of the tube. These stop-nuts are adjustable, and

their position determines the downward travel of the saw.

On the bedplate by a thumb-screw H' is secured an adjustable T-shaped gage H, with its face portion raised to permit the passage of small particles of ice under it. The bedplate is also provided with a channel or groove near the edge and a transverse grooveY across the middle to drain the water off. A guide J is provided to prevent the small blocks of icle from wedging against the rim of the bedp ate. l

While primarily designed for an ice-cutting machine, it is obvious the principle of this machine is applicable to many processes requiring a guided saw with'wide-set teeth.

What I claim as new, and desire to secure by Letters Patent, is-

i l. In an ice-cutting machine, lthe cpmbination with a bed-plate, of upright longitudinally-slotted tubes, passing through and secured to the bed-plate near opposite edges thereof, having caps on their upper ends, each provided with a taper plug adapted to enter the end of the tube.

IOO

2. In an ice-cutting machine, the combination with a bed-plate, of upright longitudinally-slotted tubes, passing through and secured to the bed-plate near opposite edges thereof, having caps on their upper ends, each provided With a taper plug adapted to enter the end of the tube, and a saw passing through both slotted tubes.

8. In an ice-cutting machine, the combination With a bed-plate, of upright longitudinally-slotted tubes, passing through and secured to the bed-plate near opposite edges thereof, a slotted guide-bar sliding Within each tube and having flanges extending through the slots of the tube and a saw passing through both guide-bars and both slotted tubes.

4. Y In an ice-cutting machine, the combination with a bed-plate; of upright longitudinally-slotted tubes passing through and secured to the bed-plate near the opposite edges thereof,.slotted guide-bars sliding Within the tubes, and ,having flanges extending through the 'slots of the tubes and their lower ends located at a point above the saw-teeth, and a saw passing through both guide-bars and both slotted tubes. 4

In an ice-cutting machine, the combination with a bed-plate, of upright longitudi.

tube and having iianges extending through the slots of the tube and a bearing located Within the guide-bars, a saw passing through both guide-bars and both slotted tubes, having longitudinal slots, each receiving a bearing and a stop-nut adjustably secured on the inside of the tube.

7. In an ice-cutting machine the combination with a table or bed-plate of an upright longitudinally-slotted tube secured therein, a slotted guide-bar sliding Within the tube having ilanges fitting the slots of the tube, aroller pivoted in the slot of the guide-bar, a saw passing through the slots of the tube and guide-bar and receiving the' roller in a longitudinal slot near its upperedge, a stop-nut secured on the inside of the tube, a cap fitting the upper end of the tube having a tapering plug adapted to enter the end or' the tube, and an adjustable raise gage secured to the bedplate.

8. In an ice-cutting machine, the combination With a table or bed, of a pair of longitudinally-slotted tubes secured in the bed-plate at right angles thereto, a pair of slotted guidebars slidingly mounted Within the tubes, anged to tit the tube-slots, each v provided with a roller pivoted in its respective slot,a saw passing through both tubes and guide-bars having afpair of longitudinally-disposed slots each receiving one of the guide-bar rollers and Working thereon, stop-nuts secured inside the tubes, caps with taper plugs adapted to enter the ends of the tubes at the top, an adjustable raised gage secured to the bed-plate.

In testimony whereof I have signed my name to this specilieation in the presence of two subscribing Witnesses.
